Step-by-step explanation:
Answer:
19.8 years old
Step-by-step explanation:
If Z=(x-μ)/σ where Z=-1.32, σ=3.2, and μ=24, then:
-1.32=(x-24)/3.2
-4.224=x-24
19.776=x
19.8
Therefore, the age of a concert attendee with a z-score of -1.32 is 19.8 years old.
Answer:
z = 0
Step-by-step explanation:
Step 1: Write equation
9z - 5 - 4z = -5
Step 2: Solve for <em>z</em>
- Combine like terms: 5z - 5 = -5
- Add 5 to both sides: 5z = 0
- Divide both sides by 5: z = 0
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
9(0) - 5 - 4(0) = -5
0 - 5 - 0 = -5
-5 = -5
